because dll's are not found. Reinstalling the program may correct this problem

Is there a question here?

here is my question: when I change the path, the .exe file is not running and why? I have a message: unable to run

Something has gone wrong with your attachment so the problem is still not clear.

I didn't know that DLL's files must be attached with the exe file in the same directory. It's a news for me!

OK, fine .

Hello there
Of course; DLL files usually have to be inside the program that runs the files directory and a location included in the system path system variable. This is due to the fact that these programs must be found and downloaded by the application during running.
